Yes, a `to-list' parameter enables `gnus-mailing-list-mode' in that
group.

,----[ (info "(gnus)Group Parameters") ]
| ‘to-list’
|      Address used when doing ‘a’ in that group.
| 
|           (to-list . "some@where.com")
| 
|      It is totally ignored when doing a followup—except that if it is
|      present in a news group, you’ll get mail group semantics when doing
|      ‘f’.
| 
|      If you do an ‘a’ command in a mail group and you have neither a
|      ‘to-list’ group parameter nor a ‘to-address’ group parameter, then
|      a ‘to-list’ group parameter will be added automatically upon
|      sending the message if ‘gnus-add-to-list’ is set to ‘t’.
| 
|      If this variable is set, ‘gnus-mailing-list-mode’ is turned on when
|      entering summary buffer.
| 
|      See also ‘gnus-parameter-to-list-alist’.

Did you check its value in the *Summary* buffer of the corresponding
gmane group?
